摘要

As for this invention, it regards the valve operation system and the method of being used for the internal combustion engine which has the piston and at least one which possesses the engine valve combustion cylinder. This valve operation system, the hydraulic pump, has the high pressure reservoir, and the electromotive hydraulic valve actuator. The hydraulic pump is formed in order to cause hydraulic output on the basis of at least the external form of the gap between the valve - pistons of one cylinder of the internal combustion engine. The high pressure reservoir is connected to the hydraulic pump. The electromotive hydraulic valve actuator, through the 1st control valve, is connected by the high pressure reservoir, in order to operate at least one engine valve of the internal combustion engine according to the output of the hydraulic pump, is constituted. Selective figure Figure 1 In addition Conclusion number, because it makes the Japanese prescribed form correspond, differs from those of statement in international publication communique, but there is no modification in contents of translation.
